You make a very good point about ROI for non-obvious investments. I also agree with you that for many things like your general repair example, humans are better than robots for the time being. That's why I framed it as them having "the potential" to perform better. I think most would agree that our on-site manual superiority isn't going to last very much longer in the scheme of things; especially under scrutiny of cost/benefit. What I'm trying to get at is the question of where we see humans' roles over the coming centuries with respect to space travel, and whether the sci-fi trope of humans on ships and colonizing planets on foot makes sense or is really something to aspire to, and at what point that falls apart as a utilitarian approach. I agree it's not yet, but I agree with @lukifer that we'll outgrow ourselves as our technological grasp exceeds our biological one. And our reach has never known any bounds.
